That means, exposing to the user only the '--without-cuda-driver' behavior:
including the GCC-shipped 'include/cuda/cuda.h' (not system <cuda.h>), and
'dlopen'ing the CUDA Driver library (not linking it).
For development purposes, the libgomp nvptx plugin developer may still manually
override that, to get the previous '--with-cuda-driver' behavior.

Remove.
